This project is easy and really difficult to screw up. What makes its incredibly difficult if finding the room when you're doing this on the ground. I had more time in figuring out how to get my hands and tools in the right spot than actually fixing the issue.

I had to use a socket to mostly remove the bolt. Once it's hand loose, you'll hand to toss the socket and use your fingers to finish removing the bolt.

On the linkage, I used a ratchet wrench to pop the nut loose. I then used an adjustable wrench to get the large nut loose but it was just a little more than finger tight so it wasn't as difficult as it could've been.

Good luck, John!
